Chronic fatigue syndrome is diagnosed through detection of an about 30 kDa RNase L molecule under native conditions in cellular extracts of RNase L-containing cells such as peripheral blood mononuclear cells. Proteins are fractionated according to molecular weight under non-denaturing conditions. The fractionated proteins are assayed for the presence of the about 30 kDa protein having 2-5A-dependent RNase L enzyme activity. The severity of the affliction may be determined by testing for the presence of RNase L molecules having approximate molecular weights of 30 and 80 kDa. The presence of the about 30 kDa RNase L, and the absence of the about 80 kDa RNase L molecule, correlates with severe chronic fatigue syndrome. The presence of both RNase L molecules indicates a less severe chronic fatigue syndrome affliction. Under de-naturing conditions, and in the presence of protease inhibitors, chronic fatigue syndrome may be diagnosed through the detection of an about 37 kDa 2-5A binding protein.
